I want a web page that has some decent information because I may expand on my trivial implementation to support additional functions. Thus I want to start with a good design that can be generalized (which is why I am asking). Sorry for any confusion. I'd like to make a simple infix expression evaluator. It should be able to support simple functions, such as *, +, -,/ as well as simple recursion. That is, if I define G <- 19 H <- G + 6 evaluate G should return 25 Anyone know a good webpage for some info? cheers, Micha __________________________________________ Micha Pringle Systems Development TISCOM Systems Albisriederstrasse 365 CH-8047 Zurich Switzerland Tel: +41 (0)1 405 60 80 Fax: +41 (0)1 405 60 99 e-mail: micha.pringle@tiscom.com __________________________________________ _______________________________________________ Hugs-Bugs mailing list Hugs-Bugs@haskell.org http://www.haskell.org/mailman/listinfo/hugs-bugs
